Abstract

a presente invenção refere-se a um sistema e método para gerar imagens em alta resolução usando uma câmera plenóptica tendo uma lente principal na frente de uma matriz de microlentes e um sensor de imagem, caracterizado pelo fato de que compreende: captar um primeiro conjunto de imagens em um primeiro estado de operação não excitado usando um meio birrefrigente disposto entre uma referida lente principal e uma referida matriz de microlentes, o referido estado não excitado do referido meio birrefrigente provendo um raio ordinário a cada pixel; fazer com que o referido primeiro estado não excitado se torne um segundo estado excitado por aplicação de uma tensão através do referido meio birrefrigente; captar um segundo conjunto de imagens no referido segundo estado excitado, o referido estado excitado do referido meio birrefrigente dividindo a luz da referida lente principal em um raio ordinário e um raio extraordinário, o referido raio extraordinário sendo deslocado por uma distância de um meio pixel do raio ordinário no referido sensor de imagem; subtrair o valor de pixel associado com o referido primeiro conjunto de imagens de pelo menos duas vezes o valor de pixel associado com o referido segundo conjunto de imagens, e gerar um conjunto final de imagens com alta resolução a partir da referida subtração e do referido primeiro conjunto de imagens.
